Method for electrically contacting an electrically actuable fuel injection valve

Abstract

A known fuel injection valve that can be secured to a fuel distributor by rotating the fuel injection valve about a longitudinal valve axis. A first electrical contact element extends out of the valve housing, parallel to the longitudinal valve axis. Such fuel injection valves can be electrically contacted by a bank of contacts that can be mounted on the fuel distributor in a direction of the longitudinal valve axis. The novel fuel injection valve includes first electrical contact elements which extend radially outward. By rotating the fuel injection valve about its longitudinal valve axis, an electrically conductive connection can be made between first electrical contact elements and second electrical contact elements that electrically contact the connection in the fuel injection valve. In this way, a simple, very compact, safe and secure electrical contacting of the fuel injection valves is attained. The electrically actuatable fuel injection valve according to the invention is especially suitable for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

What is claimed and desired to be secured by letters patent of the United States is: 
     
       1. A method for electrically contacting a fuel injection valve, which comprises forming a valve housing (10) with a longitudinal axis (7), forming at least one first electrical contact element (79) on said housing (10) of said fuel injection valve (1) radially of said longitudinal axis (7) serving the purpose of electrically contacting said fuel injection valve, forming a cover means for said housing (10), forming at least one second electrical contact element (45) on said cover means radially of said fuel injection valve, rotating the fuel injection valve (1) and the at least one first electrical contact element (79) about the longitudinal valve axis (7) to secure said at least one first electrical contact element (79) to said at least one second electrical contact element (45) to establish an electrically conductive contact between the at least one first electrical contact element (19) of the fuel injection valve (1) and the at least one second electrical contact element (45) and simultaneously securing said fuel injection valve to said cover means (5). 
     
     
       2. A method as defined by claim 1, in which the fuel injection valve is secured to said cover means (5) by means of a bayonet mount (29).
